Rich Felker	2e5d256984	fix sendmmsg emulation return value for zero-length vector ... this case is not even documented, but the kernel returns 0 here and it makes sense to be consistent.	2014-06-20 02:13:38 -04:00
Rich Felker	acb7e049b8	implement sendmmsg and recvmmsg ... these are not pure syscall wrappers because they have to work around kernel API bugs on 64-bit archs. the workarounds could probably be made somewhat more efficient, but at the cost of more complexity. this may be revisited later.	2014-06-19 23:01:15 -04:00
